The OpenWSN project is an open-source implementation of a fully standards-based protocol stack for capillary networks, rooted in the new IEEE802.15.4e Time Synchronized Channel Hopping standard. IEEE802.15.4e, coupled with Internet of Things standards, such as 6LoWPAN, 6TiSCH, RPL and CoAP, enables ultra-low-power and highly reliable mesh networks, which are fully integrated into the Internet. OpenMote is an open-hardware platform designed to facilitate the prototyping and technology adoption of IEEE802.15.4e TSCH networks, and is fully supported by OpenWSN.

The Internet of Things (IoT) is expected to be the next ‘big thing’. To date, however, there is no de facto standard software platform to program memory and energy-constrained IoT devices [1]. We expect an evolution of IoT software platforms that can be roughly compared to the recent evolution of software platforms powering smartphones.
